Definitions

  • the invention refers to a ball joint device of the type used in automotive industry.
  • European patent EP 0481212 shows a ball joint with a ball head, a pivot pin and a ball joint pin housed in a joint casing with a pot-shaped interior, in which it can be moved in a pivoting manner.
  • the ball joint is assembled in a sliding manner in a bearing joined to the joint casing.
  • the device has an annular projection radially extending outward touching the front face of the side of the opening of the joint casing.
  • US2004/105722 discloses a ball-and-socket joint for a motor vehicle, especially for a rocker pendulum of a motor vehicle, provided with a housing, which is open on at least one side and into the interior space of which a bearing shell is inserted, which in turn accommodates a joint ball of a ball pivot in a slidingly movable manner.
  • the interior space has elevations and/or depressions along its inner jacket surface or a polygonal cross section, so that the bearing shell, which is provided with an oversize in relation to the inner jacket surface, can be inserted into the housing in a positive-locking manner while its outer surface undergoes a partial plastic deformation.
  • the inner jacket surface may have pressure zones which shorten the effective length of the elevations and/or depressions.
  • the embodiments proposed in the state of the art require a precise adjustment both in the manufacture and in the subsequent assembly of the components of the device. This high degree of precision in the manufacture is necessary because it could even occur that the assembly is not possible if the tolerances of the components are too broad or if, even in the case of being more restrictive, the manufactured parts do not comply with said design tolerances; these tolerances will also have an effect on the functioning of the device.
  • Ball joint devices with inappropriate tolerances cause a series of inadmissible flaws. In addition to being noticeable in a recently manufactured device, these flaws imply a premature deterioration of the device, shorten its useful life and affect the use of the device.
  • auxiliary elements are usually protective domes with their corresponding retaining or sealing elements joining said protective domes with the rest of the components of the ball joint device.
  • Another additional feature which ball joint devices must have is modularity, this being understood as the ability to constitute a module integrated in a system which said ball joint device is a part of.
  • the devices known in the state of the art have a design and construction which does not facilitate this ability to be integrated in a system in a manner easily adaptable to different systems, given that to that end, they require that the system itself is modified.
  • the present invention proposes a ball joint device solving the drawbacks in the state of the art set forth above.
  • joining means and the contact areas of the components of the ball joint device on the joint surfaces assures the leak-tightness required in this type of devices.
  • Said joining means also allow simplifying the process of manufacturing the device, given that leaks in the contact areas are absorbed by the configuration itself of said means; the notching or grooving included in the contact areas between the casing and the ball joint seat.
  • the relationship between the casing and the seat can also allow the casing to be designed such that it can be adapted to different applications according to the system in which the ball joint device is going to be incorporated.
  • the casing and the seat define a housing in which the protective dome is joined at one of its ends to the ball joint device; the use of a retaining element for said protective dome is thus prevented, achieving a reduction of the cost of the device, both by decreasing the number of components and by simplifying the assembly.
  • the invention describes a ball joint device comprising:
  • the frustoconical portion in the casing and the conjugate frustoconical portion in the seat can be provided with grooving, a striated surface, for:
  • the first joining means can also comprise an annular projection in the casing and a first annular groove in the seat for holding the seat to the casing, wherein the annular projection and the annular groove can be located in a first frontal contact surface between the casing and the seat.
  • the second joining means can further have a grooving for:
  • the seat can also comprise a plurality of grooves in a first seat end to facilitate:
  • the seat can also comprise a plurality of channels in an inner surface of the seat housing, said channels being configured to allow a distribution of a lubricant between the first ball joint portion and the inner surface of the seat housing.
  • the device of the invention can comprise a protective dome to protect the ball joint device.
  • the device of the invention can comprise a sealing ring to hold a first end of the protective dome to the ball joint.
  • the protective dome can comprise a plurality for annular grooves in the manner of a labyrinthine seal in a contact surface between the first end and the ball joint to assure leak-tightness between the protective dome and the ball joint.
  • the device of the invention can further comprise:
  • the casing can be of a material selected from:
  • the casing can comprise a body formed by a plurality of parts.
  • the ball joint seat can be of a material selected from:
  • the ball joint seat and casing can be joined by means of a process selected from welding, riveting and combinations thereof.
  • the protective dome can be of an elastomeric material selected from:
  • the sealing ring can be of a material selected from:
  • Figure 1 shows a cutaway view of the device of the invention showing the different components assembled.
  • Figure 2 shows a perspective view of the protective dome from the side of the first end of said protective dome and of the sealing ring.
  • Figure 3 shows a perspective view of the protective dome from the side of the second end of said protective dome.
  • Figure 4 shows a perspective view of the ball joint.
  • Figure 5 shows a perspective view of the seat from the side of the first end of said seat.
  • Figure 6 shows a perspective view of the seat from the side of the second end of said seat.
  • Figure 7 shows a perspective view of the casing from the side of the first end of said casing.
  • Figure 8 shows a perspective view of the casing from the side of the second end of said casing.
  • Figure 1 depicts an embodiment of the device of the invention in which the different components are shown assembled.
  • FIGs 5 and 6 the seat 2 is shown in its configuration before being assembled in the device; in Figure 1, the seat 2 after having been introduced in the housing 10 of the casing 1 can be observed. In this sense, Figures 5 and 6 show an area of the seat 2 which once formed, together with the second casing 1 end 12, constitutes the first frontal contact surface 1202 and the first peripheral contact surface 1201.
  • the joint between the casing 1 and the ball joint seat 2 is carried out according to the materials of said casing 1 and seat 2. If the joint between the materials is plastic-plastic, the joint will be welding; should one of the materials not be plastic, the joint will be riveting.
  • both the casing 1 and the seat 2 incorporate notching.
  • Figures 5 and 6 show the notching in the seat 2, whereas the notching of the casing 1 can be seen in Figures 7 and 8.
  • the casing 1 incorporates an annular projection 123
  • the seat 2 incorporates an annular groove 124.
  • the annular groove 124 can also be carried out in the casing 1, the seat 2 then incorporating the annular projection 123.
  • Said housing means 30 allow housing a second end 32 of the protective dome 3, preventing using an additional mechanism, such as a sealing or retention ring, to secure the second end 32 of the protective dome 3.
  • Said housing means 30 comprise:
  • Said second annular groove 33 and third annular groove 34 define an annular cavity having a volume equal to the volume of the second end 32 of the protective dome 3.
  • the second end 32 becomes deformed in order to occupy the volume defined by the second annular groove 33 and third annular groove 34.
  • Figure 5 shows the channels 24 engraved in the inside wall or inner surface of the housing 20 of the seat 2. Said channels 24 allow for the distribution of a lubricant between the first ball joint portion 40 and the inner surface of the seat housing 20.
